cloud-proxy-hub

Multi-provider proxy pool with geo and performance validation. Wraps Proxy-Seller (datacenter + residential), SmartProxy (residential) and pingnetwork.io (residential, secondary) behind a single class:

from cloud_proxy_hub import ProxyHub, ProxyHubConfig

config = ProxyHubConfig(
    # provider credentials — or leave unset and export the same-named
    # env vars (PROXY_API_KEY, SMARTPROXY_LOGIN, SMARTPROXY_PASS, ...)
    proxy_api_key="...",
    proxy_seller_res_login="...",
    proxy_seller_res_pass="...",
    proxy_pingnetwork_res_login="...",
    proxy_pingnetwork_res_pass="...",
    smartproxy_login="...",
    smartproxy_pass="...",

    # extra static datacenter proxies per ISO-3166 alpha-2 country code
    # (used to be hardcoded in the library — now it's yours to supply)
    additional_datacenter_proxies={
        "ZA": ["http://user:pass@host:port", ...],
        "BR": ["http://user:pass@host:port", ...],
    },

    # which providers are active, and in what order (default shown here —
    # SmartProxy is OFF by default; add it back with any key/priority to
    # re-enable, e.g. provider_priority={"Proxy-Seller": 1, "SmartProxy": 2, "pingnetwork": 3}).
    # Drop "pingnetwork" too if you don't want the pingnetwork.io fallback.
    provider_priority={"Proxy-Seller": 1, "pingnetwork": 2},

    # tuning knobs, passed the same way at startup — shown with their defaults
    proxy_seller_weight=90,     # % of residential traffic via proxy-seller.com
    pingnetwork_weight=10,      # % via pingnetwork.io
    smartproxy_retries=5,
    smartproxy_backoff_factor=1.5,
    smartproxy_timeout=10,
)

proxy_hub = ProxyHub(validate_proxies=True, config=config)

proxy = proxy_hub.provide_valid_proxies(
    proxy_type="residential",
    country_code="DE",
    neighbor_geo_enable=False,
    reverse_proxy=is_last_attempt,  # force pingnetwork.io on the last retry
)

Everything you need to tune lives on ProxyHubConfig — construct it once, pass it to ProxyHub, and call provide_valid_proxies(). No need to reach into cloud_proxy_hub.providers / cloud_proxy_hub.geo / cloud_proxy_hub.performance unless you're extending the library itself.

Why a config object

The original script read paths and provider credentials from an internal src.settings module, and had a dict of extra datacenter proxies (with real login/password pairs) hardcoded in the class body. Both made the code impossible to hand to anyone outside that one codebase, and unsafe to publish anywhere public. ProxyHubConfig replaces both: every credential is either passed explicitly or read from an environment variable of the same name, and additional_datacenter_proxies is supplied by the caller instead of baked into the source.

Install

pip install cloud-proxy-hub

Published on public PyPI. No credentials are embedded anywhere in the source — every secret is supplied by the consumer via ProxyHubConfig or environment variables, as shown above.

Publishing a new version

python -m pip install --upgrade build twine
python -m build          # produces dist/*.whl and dist/*.tar.gz
python -m twine upload dist/*

Requires a PyPI account with 2FA enabled and an API token (__token__ as username, the token as password).

Migrating from the old updated_proxy_hub.py

• from src.settings import settings → build a ProxyHubConfig(...) once (from your own private settings) and pass it to ProxyHub(config=...).
• The hardcoded ADDITIONAL_DATACENTER_PROXIES dict → pass it as ProxyHubConfig(additional_datacenter_proxies={...}).
• The hardcoded proxy_priority module dict (which providers run, and in what order) → ProxyHubConfig(provider_priority={...}). Default is {"Proxy-Seller": 1, "pingnetwork": 2} — SmartProxy is off by default (still fully implemented in the library, just excluded from the default dict); add an "SmartProxy": <n> key to turn it back on, or drop "pingnetwork" to disable that too. Same membership check for all three — drop any key to disable that provider at startup instead of commenting it out in library source. Caveat: "pingnetwork" only runs from inside Proxy-Seller's residential lookup, so dropping "Proxy-Seller" disables pingnetwork too even if "pingnetwork" is still in the dict — see USAGE.md for details.
• The hardcoded 90/10 provider split → proxy_seller_weight / pingnetwork_weight on ProxyHubConfig (defaults are still 90/10).
• SmartProxy's hardcoded retries=5, backoff_factor=1.5, timeout=10 → smartproxy_retries / smartproxy_backoff_factor / smartproxy_timeout on ProxyHubConfig (same defaults).
• ProxyHub(validate_proxies=...) and provide_valid_proxies(...) keep their original signature and behavior.
